Advertized-Announced Prefixes.

!prefixes displays the IP prefixes announced or advertised in BGP by an Internet Autonomous System (AS).

Autonomous Systems announce IP prefixes that they know how to reach and are willing to provide transit for. These announcements form the global routing table and describe the networks reachable through each AS.

This command accepts one Autonomous System Number (ASN) and returns the set of IPv4 and IPv6 prefixes that the AS advertises.
